BXREBEI z, a citizen oi the L'Plittl Qtates, residing-at i in- ;ag ,1ntlie county of ook and State 1 l ill!- nois, have invented eertain new ant aset'nl 'improvements in Anlil'rietion iiaterahliw tion Center-Bearings; and l do hereby do elare the following to be a hill, elear, and e. art deserig'ititm ol' the invention, stieh as will enable others skilled in the art to whR-h it appertains to malte and use the same.

My present invention has for its object to provide a simple and eliieient antilrie'ti n lateral-motion rent(r-bearing l'or railwr carsand the like and is in the nature of improvement on the latera'l-motion ren bearing disclosed and broadtv elaimed in m United States iatent Xo. 554E510, issued (ti (late August '24, .397, and entitled Car: truck. v

To the above ends the imention eonsists ol the novelrdeviees and eombimitions otiteviees'hereinal'ter deseribed, and defined in the elaims.

I {5p intil rietion-bearing deyiees are interposed between the lower bearing member 4 and th intermediate bearing member 7 and also he "tween said intermediate bearing member 7 and the upper hearing member 5.

v These 85 antitrietion devices in the 'lirs't, instance are m the torm of cylindrical rollers S), and in the seeoad instance they are in the form of coni'eal rollers 10. The said rollers 'tl are, as

Conical rollers 10 are arranged radially '10 :with respect to the axis of the center-bearing,

longitudinally and they engage with annular bearing-sun l, "faces 14 and 15, respectively, on the under surface of the bearing member 5 and on the l upper surface of the bearing member 7. The I :5 ,said bearing-surfaces 1.4 and 15 are of, such i conical form that they properly engage the interposed conical rollers 10 from end to end. Surrounding the annular bearin -surface 14 the upper bearing member 5 is ibrmed with adependin annularstop-shoulder 16, against which the .arge outer ends of the rollers 10 I engage, and surrounding the annular bearingi surface 15 the intermediate bearing member l 7 is tormed with an annular stop shoulder or flange 17, with which the large outer ends of the said conical rollers 10, also engage. Also, as shown, the upper bearing member 5 is i formed with a depending annular flange 18, i

. that surrounds the stop flange or shoulder 17 3o 01 said bearing member 7. The conicalbearing-rollers 10 are, as shown, l coupled together and spaced apart by a novel device disclosed and claimed in my ending i application, Serial No. 321,153, filed une 11, i

5 1906,entitled Antifricticn center-bearii'igs for cars. This spacing and coupling device may, therefore, in this application be briefly noted asfollows: The said conical rollers 10 at their inner ends are provided with trun- 4o nionslt), that project through a couplingring 20, which coupling-ring is supported by l the said trunnions and works freely in annuliar recesses 21 and 22, formed, respectively, in bearing members 5 and 7, Pins 23, passedthrough the inwardly-projected ends of the trulinions 19, hold the said rollers coupled to said ring 20 when said rollers and ring are removed from. working position. .The radial spacing-arms of the couplingring are not shown in the accompanying drawings.

The intermediate transversely-movablc bearing member 7 at its sides is, as shown, provided with depending guide-flan 24, that embraces the sides of the contra upper portion ofthe truck-bolster 2 and hold the i same against movements transversely of said bolster for transverse movement with rein presence of two witnesses.

\ bolster, but permit the free travelin movements thereof longitudinally of said olster.

A lateral-motion center-bearing of the character above described permits the desired lat .ral movement of the car-body with respect to the't'rucks, or vice versa, and

makesit unnecessary to mount the truckspe'ct'to the car-truck. In fact, with this arrangement the truck-bolster may be rigidly secured to the truck-frame; but prefer ably and usually it would be spring-mountedc for vertical movements on the truck-frame, but would be held against endwise movements transversely thereof.

What I claim is- 1. The combination with a truck-bolster 'havin concave roller-bearing seats formed direct y thereon, of a body-bolster provided with an upper bearing member, and an inter mediate bearing member pivotally connected to said upper bearing member and having concave roller-bearing seats in its under sur- 8o face,cylindrical rollers interposed between the seats of said lower bearing member and of said intermediate bearing member, radially-disposed conical rollers interposed be tween said intermediate bearing member and said upper bearing member, and a device '5 holding said conical rollers spaced apart, substantially as described. I r

2. In a'lateral-motion center-bearing, upper and lower and intermediate bearing members, said upper and intermediate bear in g members having axially-aimed pintle-engagin sleeves, one of which is telescoped into t e other, and the sleeve of which intermediate bearing'member works ina slot in said lower bearing member, substantially as described.

3. In a lateral-motion center-bearing, upper and lower and intermediate bearing members, said upper and intermediate bear roe ing members having pintle-engaging sleeves,

one ofwhich is telescoped into the other, and

the sleeve ol which intermediate bearing 1 member works, in a slot in said lower bearing member, 1r combination with bearing-m ners mterposed between. said intermediate bearing member and said upper and lower bearing members, substantially as described.
